The Dark Side is calling
There are a few issues concerning the amount of the GCAA salary. Two of the bigger ones are a) Is it big enough to attract ATCOs from abroad and b) Is it enticing enough to draw SERCO ATCOs to the Dark Side.
The first part is much more complex as each foreign ATCO has a very different stack of apples and oranges to compare.
The latter is starting to become more clear as, rumor has it, there are 6 SERCO ATCOs that will switch to the Dark Side in mid-September if SERCO stands put on its present package or, and most likely, announce another delay tactic.
ANSA is correct, the clock is ticking. Either SERCO makes a decision, or the decision will be made for them.
